    • A headphone receiver apparatus for use with low power transmitters includes a pair of headphone speaker enclosures connected by a headband. An antenna element in the form of a spring steel band or a plastic cable/antenna band where one of the conductors is utilized as the antenna is configured generally concentric with but offset from the headband and the user's head by at least 0.5 inches over at least some length of the antenna. Low-noise performance is improved by a low noise amplifier incorporated before the receiver IC, and a bandpass filter interposed between the low noise amplifier and the receiver IC. A base-loading inductor is used to tune the antenna element to resonance, with or without capacative end-loading. Lumped inductors, ferrite beads, or a parallel resonant LC circuit may be used to isolate the shield conductor at RF frequencies, and/or to reduce the loading of the other conductors.

    • A circuit and method of providing an auto-on and/or auto-off capability for an audio device, of a type having an audio plug which mates with the output jack of an audio source. The portable transmitter modulates audio signals from the audio source onto a carrier and transmits them to a receiver. The auto-on and auto-off capability is provided to prolong battery life and degradation of the transmitter circuit and comprises pinching off a FET when the circuit is in an “off” state. This occurs when a pre-determined threshold in a capacitor is reached by not discharging that capacitor. The capacitor is discharged by dropping a comparator input below a pre-determined threshold limit when presented with an audio peak and wherein the drop in value causes the comparator output to go low, causing the capacitor to discharge and causing the FET to supply power to the regulator.
    • 一种为音频设备提供自动启动和/或自动关闭功能的电路和方法,其具有与音频源的输出插孔相配合的音频插头的类型。 便携式发射机将来自音频源的音频信号调制到载波上并将其发送到接收机。 提供自动启动和自动关闭功能,以延长电池寿命和发射机电路的劣化,并且包括当电路处于“关闭”状态时夹紧FET。 当通过不释放该电容器来达到电容器中的预定阈值时,会发生这种情况。 当呈现音频峰值时,通过将比较器输入降低到预定阈值极限以下来使电容器放电,并且其中该下降值使比较器输出变低,使得电容器放电并且使FET向 调节器
